Answer 1

这个PyCharm问题的发生是因为iPythonapi与iPython版本5 的更改.直到Jetbrains修复此问题,恢复到早期版本iPython(版本4)才能解决这个问题.正如@chenfei发现的那样,这可以通过pip以下方式完成:

$ pip uninstall ipython
$ pip install ipython==4.2.0

编辑

如果你不能等那么久,Jetbrains已经发布了补丁

最终编辑

这个问题已在PyCharm 2016.2中修复

Answer 2

我通过安装ipython版本4.2解决了我的问题:

pip uninstall ipython
pip install ipython==4.2.0

Answer 3

我设法解决这个问题没有降级的方式iPython是:

1 - 下载以下补丁:

https://youtrack.jetbrains.com/_persistent/pycharm_ipython5_fix.patch?file=74-327779&c=true

2 - 在里面PyCharm,创建一个位于以下位置的新项目:

<PyCharm installation folder>/helpers/pydev/_pydev_bundle/

Pycharm将提示您导入该文件夹上的文件,接受.

3 - 单击VCS并选择Apply Patch

4 - 选择您在步骤1中下载的文件.

5 - Apply Patch窗口将打开,单击OK

6 - 重启PyCharm

Python控制台现在应该在里面工作 PyCharm

PS:您可以删除在步骤2中创建的项目文件夹(.idea)
